Aloha and Happy Holidays! We are now past “Nutcracker” season, so here’s a brief post for your post-holiday thoughts, as you gear up for the New Year:

Dr. Matt Wyon, PhD, our Dance Wellness Panel member and current President of IADMS, has done some research on the benefits of dancers incorporating Power Plate / “Vibration Training” into their conditioning program, which he shares in the post below. If you have access to this type of equipment, you might well investigate using it…

It is now a recognized fact that that dancers need to do supplemental training, but what can be fitted into an already hectic schedule without taking up lots of time?

Vibration training (or Power Plate training) has been shown to improve jump height and developpé height after just 8 sessions(2 ten-minute sessions per week).

In a recent study, published in the Journal of Strength and Conditioning, Marshall and Wyon had dancers hold 9 positions while on the Power Plate, for 30 seconds each for the first two weeks, and then for 40 seconds for the subsequent two weeks. The positions were:

plié in firstplié in secondrelevépelvic bridge (back on the floor and feet on the platform)right leg leading lunge with front foot on the platformleft foot leading lungebent over hamstring hold (with a right angle between torso and legs)right leg developpéleft leg developpé(the extension phase of these last two exercises were held for 2-5 seconds)

All the dancers who did the training increased their jump height 4 cm and their developpé height by approximately 20-degrees.

The important thing to remember with everything is that quality is much more important that quantity. This is especially true of supplemental training, and vibration training seems to be able to provide good results with little time demands.

Hau’oli Makahiki Hou! — That’s Happy New Year in Hawaiian! I hope everyone had a wonderful holiday — and“Nutcracker” season — and are ready to start the New Year. This month’s post is a brief one to help you with your stretching. New research (on dancers) shows that the intensity of your stretching doesn’t have to be extreme in order to increase your flexibility.

The post is written by Matthew Wyon, PhD, who has written for our Dance Wellness column before — Matt is currently serving as the Vice President of IADMS (International Association for Dance Medicine and Science), and is also a professor / researcher at the University of Wolverhampton (UK), as well as being affiliated with England’s National Institute for Dance Medicine and Science.

So — enjoy the post, and have a good start to your New Year of dancing longer, stronger, and safer!

Dancers are renowned for their flexibility or range of movement, and devote a lot of time maintaining and enhancing this attribute. There has been much written on the different stretch techniques such as static, dynamic and proprioceptive neuromuscular facilitation (PNF) and when they should be implemented — for example, dynamic stretching during warm-up and static during recovery. However, the intensity at which the stretch should be held has had little research until recently. We often feel that unless the stretch is just below the pain barrier, the point where the muscle starts to wobble, nothing will change; this often equates to “8 out of 10” intensity.

A series of recent studies has started to challenge this concept. The first showed that at 8/10 intensity there was a huge increase in inflammation blood markers, suggesting that the muscle being stretched was actually being traumatized — but at lower intensities (3-6/10) this effect wasn’t noticed.

But will this lower intensity help increase flexibility?

A six week experiment on dancers who were split into one group that stretched at their usual intensity (8/10), and another at the lower intensity (3-5/10), noted that the dancers in the lower intensity group increased their grande battement and developpé height. The second group (8/10 intensity) saw a very slight but not significant increase (5-degree) compared to 20-degree for the low-intensity group.

So it seems less is more when it comes to stretching intensity!

It must be emphasized that this intensity should be used at the end of the day as a recovery and improving range of movement technique, rather than during warm-up.

Prof. Wyon is Vice President of the International Association for Dance Medicine & Science and a past chair of the Research Committee. He has worked with numerous dancers and companies within the UK and Europe as an applied physiologist and strength and conditioning coach.

He has published over 80 peer-reviewed articles in dance medicine and science.
